Okay, since calories is y, and minutes is x we have two points: (15,150) and (20, 200) Using the slope formula we can find the slope, recall that it is: y2y1 / x2x1 200  150 / 20  15 = 50/5= 10 What does it represent, well slope is rise over run, on this rise you have have calories and run is minutes, so it's calories/minute, or the rate at which calories are burned. For part three we need to make an equation. We have the slope and a point, so it's not to bad. Recall that (yy1)=m(xx1) y200=10(x20) y200=10x200 y=10x Okay, now that we have that we can plug in 35 for x, and find that they will burn 350 calories. :D
